TOPAZ is owned by the Shanghai Tongzhi Auto Parts Co., Ltd.
They are an aftermarket parts distributor. They source parts from many unaffiliated manufacturers, almost all Chinese. They are likely not an OEM provider of much of anything They are like a Rein in that they make little on their own. |

Anyway, the TYC fan I bought is great, and in conjunction with the hi-flow aftermarket electric puller fan I had already installed, both fans make my engine cooling reliable, and A/C cool down to 38F (as measured on 90F days). Sent from my SM-G965U using Tapatalk |
workingonit,
No worries. I keep a spreadsheet to record parts and maintenance. I should probably delete the cost column though. |

When building the Chevelle, I started building it at home, but my wife found my spreadsheet with costs and future costs, so I quit working on it at home and only did so at my friend's shop, 50 miles from home...out of sight and out of mind of my wife, hahaha. I just resorted to giving my friend/race car builder about $150 a week and he'd buy the parts for me (at a good discount from his ring of sources), and work off the extra costs at his shop every weekend. We'd work on my car, other cars in our race team, and those of his outside customers. The $150 I'd automatically hand over was just some overtime pay I'd always get (for most of 47 years, I was always the first one in and last one out at work, so OT was a given). On the home-made trailer, I started it out with another spreadsheet, and kept it and the trailer in my friend's shop (after I had quit dragracing), so no worries about the wife snooping and sniping about the costs. But, about halfway through the build (after 11 months), I brought it home into my garage to finish it out (it was a completed exterior shell at the time), and I couldn't hide it anymore, so I just 'fessed-up. Anyway, I was building it for her to use anyway. She was a member of a Bigfoot hunting group, which would travel to and camp in some wild areas, all over the country; I was wanting a safe, dry, and heated/cooled trailer to replace her crummy tent. So, I showed it to her, and continued to build it in plain sight. When finished, it was too late, as she quit Bigfoot hunting and stayed home, while I took up occasional camping instead (only about 15 days a year, max...much less time than my racing days). Now, the trailer sits unused in the garage and the Chevelle was traded for the X5 in May of '21. No spreadsheets or secret builds anymore. Sent from my SM-G965U using Tapatalk |
Just did a quick test using INPA setting the aux fan at 30%; no spin at all. I'll be testing the new fan before I even bother removing the front bumper. This car is nerve racking sometimes, but I love it.

Test for voltage on the power cable before you pull the fan.
I was able to plug in my fan on e 70 while it was on top of the motor. (If fan is disconnected, the water pump runs at full speed). I had to drill out a couple screws holding the bumper cover. Seized spring nuts just spun. I used some wall anchors and fender washers to reattach. |
Yes, test for voltage before replacing. There is a 50A fuse that can blow. My failed fan turned out to be a $3 fuse.
|
The fuse always blows for a reason and often because the fan is on it's way out so if mileage on the fan is up there it might be a good idea to replace it anyway.
|
+1 for sure especially 50A!

Quick update.
The replacement was a success. Tested the new fan with INPA before removing everything; the fan ran without problems. Ripped everything apart, replaced the old the fan, ran INPA again and the fan worked. Just in time for 80F degree weather. Thanks guys. One question though; is the aux fan triggered by the temperature read by the CTS on the lower radiator hose? |
